i had one coming on today a bad one where the bottom has dropped out of the temps i know theyve taken darvocet & darvon off the market 4 now but its the only thing that helps so i know someone who still has some --this is how bad this one was gonna get-- i took one darvocet did not help waited 5 hours took another one & its gone thank the Lord! & yes i tried everything before i took the darv 800motrin zyrtec rx so im migraine free well until my next period or drastic barometric pressure change in weather. i know i shouldnt be so pessimistic but theyre like clockwork & predictable
